Halfway through his PhD program in neuroscience at the University of Pennsylvania, Greg Dunn was inspired to try a new experiment: using the brain structures he was seeing in the lab as the subject matter for his minimalist Asian-inspired paintings.

“In grad school, I would be looking at these images all day, and I was already on an Asian-art wavelength,” Dunn says. “One day I saw some images of Golgi-stained neurons, and I thought, ‘They’re sort of similar to these Zen paintings I’ve done.’ So I started experimenting, blowing ink around on a page. And it looked like neurons to me.”

Dunn says that was his “aha moment,” when it occurred to him that he could combine his two interests—neuroscience and art—into one pursuit.

To create a painting such as Cortex in Metallic Pastels, shown above, Dunn starts with a piece of stainless steel sheeting or metal-leafed acrylic panel. The surface is scratched, so light bounces off of it in a polarized way, Dunn says. “This allows you to control how light will be reflected.” Dunn then paints that scratched surface with a series of transparent dyes, finishing the piece with protective coatings.

Since graduating in 2011, Dunn has supported himself as an artist, but he says he’s still very much a scientist. “These are complicated paintings, with many layers. I do a full scale mock up in Photoshop and set up a protocol to follow,” Dunn says. “I’m not doing ‘science art’ because I am painting neurons. I’m approaching art scientifically, using my knowledge of physics and chemistry.”
